Ubuntu packags missing since May

[Andrew Lyons]

All releases since May are missing Ubuntu packages.

See an example of the failing build here: https://github.com/facebook/watchman/actions/runs/5505064162/jobs/10032023257

The failing build logs indicate sudo package is missing.
Looks like it could be fixed by adding sudo to this line:

I've been meaning to look at this and haven't had a chance. @xendarboh I think you're on the right track. Want to put up a PR with that fix? We should be able to tell from the PR itself whether the GitHub Actions succeed.
